How frequent are overactive bladder symptoms in women with urodynamic verification of an overactive bladder?

OBJECTIVE

To determine the relationship between overactive bladder symptoms and urodynamic verification of overactive bladder.

MATERIAL AND METHODS

Between June 2011 and November 2011, 159 patients underwent urodynamics (UDS) at our urogynecology unit in the Ege University Hospital. Of these, 95 patients who complained of urgency, did not have any overt neurological diseases, bladder outlet obstruction and did not take any medication affecting the lower urinary tract function were evaluated. SPSS (ver. 15.0) was used to evaluate the data and the chi-square test and t test for independent samples were used for analysis.

RESULTS

The mean age was found to be 54.5±12. Frequency was the most frequent symptom in women with overactive bladder (OAB) (82.1%), nocturia (57.8%) and (57.8%) urgency urinary incontinence followed in frequency. Detrusor over activity incidence was found to be 38.9%. There was no significant relationship between the presence of detrusor over activity (DOA) and OAB symptoms. Leak at urodynamics was found in 46.3% and there is no significant association with detrusor overactivity. Total bladder capacity was found to be significantly lower in women who had DOA (p=0.000).

CONCLUSION

It appears that overactive bladder symptoms do not predict detrusor over activity. Urodynamic investigation is not mandatory in the initial management of women with only OAB symptoms.
